Definitions
- the present invention relates to the use of nickel based alloys which have a combination of high strength and corrosion resistance.
- Alloys having high strength are required in some applications for sustaining stress in load-bearing service in chemically adverse environments. Some plastic ductility is also needed for enduring or permitting modest amounts of deformation without sudden fracture, for example to safeguard against accidental bending, or to enable cold forming to be carried out. Alloys having this desirable combination of properties are particularly useful for use in petroleum production tubing for oil wells, in contact with chemically adverse media such as chlorides, acids and such compounds as hydrogen sulphide. The alloys must therefore exhibit resistance to corrosive pitting, stress corrosion cracking and hydrogen embrittlement, as well as high strength.
- the prior art includes numerous disclosures, for example in GB-A-1 385 755 and GB-A-1 514 241, of age-hardenable nickel-iron-chromium alloys that are said to be very resistant to oxidation at elevated temperatures and to be suitable for fabricated parts such as aeronautical turbines or turbine casings.
- INCONEL alloy 718 as disclosed and claimed in US ⁇ A ⁇ 3 046 108, is an age-hardenable high strength alloy for service over a wide temperature range, from -250°C to 700°C, and offers good resistance to a wide variety of corrosive environments. Since the alloy also offers excellent stress rupture properties and fatigue strength, it has been used in down-hole service in oil-wells. However, the alloy has insufficient resistance to hydrogen embrittlement in the harsh environments found in "sour well” conditions and, although having high as-cold-drawn strength, has low ductility.
- the present invention is based on the discovery that certain alloy compositions, developed from alloy 718, have an excellent combination of strength and ductility in the wrought and age-hardened condition and also excellent resistance to hydrogen embrittlement and chloride stress cracking.
- an alloy consisting, by weight, of from 15 to 22% chromium, 10 to 28% iron, 6 to 9% molybdenum, 2.5 to 5% niobium, 1 to 2% titanium, and up to 1% aluminium, the balance, apart from impurities and incidental elements, being nickel in a proportion of from 45 to 55% of the alloy, is used in the form of wrought and age-hardened articles and parts in highly corrosive conditions in sour oil or sour gas wells or in sulphur dioxide gas scrubbers.
- Further elements which may be present in small amounts include up to 0.1 % carbon, up to 0.35% silicon, up to 0.35% manganese, up to 0.01% boron, and also residual small amounts of cerium, calcium, lanthanum, mischmetal, neodymium and zirconium such as can remain from additions totalling up to 0.2% of the furnace charge.
- Impurities present may include up to 0.5% copper, up to 0.015% sulphur and up to 0.015% phosphorus.
- molybdenum and niobium are often associated with tungsten and tantalum, which may be present at levels of about 0.1% tungsten and 0.1% tantalum.
- the tungsten must be controlled at a low level to avoid the formation of undesired phases such as Laves phase.
- tantalum may be substituted for niobium in equiatomic percentages, its presence is not desirable because of its high atomic weight.
- chromium iron, molybdenum, niobium, titanium, aluminium and nickel gives rise to desirable properties of strength, ductility, fabricability and durability in highly corrosive environments.
- a preferred composition for use according to the invention contains from 18.5 to 20.5% chromium, 13.5 to 18% iron, 6.5 to 7.5% molybdenum, 1.3 to 1.7% titanium, 0.05 to 0.5% aluminium, balance (apart from impurities and incidental elements) nickel.
- the titanium and niobium contents of the alloy are closely controlled such that Preferably the alloy contains 1.3% to 1.7% titanium and 3.6% to 4.4% Nb, and most preferably 1.5% Ti and 4% Nb.
- the alloy has good workability, both hot and cold, for production into wrought articles such as cold rolled strip and extruded tubing.
- Appropriate process treatments may be used to enhance the strengths of articles manufactured from the alloy. Such treatments include cold working, age-hardening and combinations of the two.
- the alloy may be annealed at a temperature of 871°C to 1149°C, and aged at 593°C to 760°C, or even 816°C. Direct aging treatments of heating the cold-worked alloy at 649°C to 760°C for from 0.5 to 5 hours directly after cold working are particularly beneficial for obtaining desirable combinations of high strength and ductility.
- Alloys of the present invention after appropriate thermomechanical processing exhibit yield strength (0.2% offset) of in excess of 1034 MN/m 2 , with an elongation of 8%, and preferred alloys have strengths of more than 1310 MN/m 2 and elongation of around 15%.
- Alloy 1 was prepared by vacuum induction melting and was cast to ingot form. Ingots of alloy 1 were heated at 1121°C for 16 hours for homogenization and then forged flat from 1121°C. Flats were hot rolled at 1121°C to reduce about 4 mm (0.16 gauge), annealed at 1066°C for 1 hour and cold rolled to 2.5 mm (0.1 gauge) strip, which was again annealed at 1066°C for 1 hour.
- Hardenability, including work hardenability and age hardenability, of alloy 1 was confirmed with hardness measurements, as shown in Table II, on specimens of the 1.27 mm (0.05 gauge) strip before and after heat treatments with temperatures and times referred to in the Heat Treatment Schedule (Table III).
- Annealed hardnesses of 20% CR strip on Rockwell B scale after treatments of 954°C for hour, 1038°C for 1 hour and 1149°C for hour were 97, 93 and 78.
- Corresponding results with 40% CR strip were 23.5 Rc, 94 Rb and 78 Rb.
- Alloy 2 and alloy 3 were air induction melted and centrifugally cast with protection of an argon shroud in a metal mould having a 10.8 cm I.D. and 1300 rpm rotation speed to produce cast centrifugally solidified tube shells of alloy 2 and 3. Cast dimensions were 10.8 cm O.D. and 1.9 cm wall thickness. The shell was cleaned up to 10.2 cm O.D. and 1.11 cm wall thickness.
- a leader tube was welded onto the shell and processing proceeded as follows.
- the tube shell was annealed at 1149°C, pickled and cold drawn (about 15.8%) to 9.525 cm O.D. x 0.99 cm wall, re-annealed at 1149°C and pickled, then cold drawn to 8.89 cm O.D. x 0.889 cm wall (also 15.8% reduction), re-annealed at 1149°C and pickled, then tube reduced to 6.668 cm O.D. x 0.762 cm wall (about 36.7% reduction in area).
- a transverse specimen taken from the extruded and 704°C direct aged product of alloy 3 was of ASTM grain size No. 3 ; optical microscopy of the specimen showed an absence of intergranular carbides and indicated that the extruded, cold-reduced and heat-treated microstructure did not contain any intragranular phases resolvable at 1000x.
- Alloys 2, 3 and E were melted, and centrifugally cast to tube shells and processed to 6.67 cm O.D. tube with 0.762 cm wall thickness by the process described in Example 2.
- Table VI compares chloride stress corrosion cracking data for these alloys at 177°C and 204°C.
- the alloy samples were prepared as stressed C-ring specimens and subjected to a simulated deep sour gas well environment comprising a 25% solution of sodium chloride plus 0.5% acetic acid and 1 g/I sulphur, the solution saturated with hydrogen sulphide to an H 2 S overpressure of 861 KN/m 2 .
- test conditions chosen for alloy E were those considered to be less prone to hydrogen embrittlement than the cold worked+aged samples of alloys 2 and 3. Despite testing at lower stress the comparative alloy failed earlier than alloys of the invention.
- the room temperature tensile data corresponding to the above corrosion data is summarised in Table VIII.
- alloys 2, 3 of the present invention exhibit a desirable combination of strength and ductility.
- Alloys of the present invention are useful for tubes, vessels, casings and supports, needed for sustaining heavy loads and shocks in rough service while exposed to corrosive media, and particularly for production tubing to tap deep natural reservoirs of hydrocarbon fuels.
- the alloys are beneficial for resistance to media such as hydrogen sulphide, carbon dioxide, organic acids and concentrated brine solutions sometimes present with petroleum.
- the alloys provide good resistance to corrosion in sulphur dioxide gas scrubbers and are useful for seals, ducting, fans and stack lines in such environments.
- Articles of the alloy can provide useful strength at elevated temperatures up to 648°C and possibly higher.
